So you want to know how to cheat death but don’t know if your ready to be frozen alive? The promise of cryonics is to preserve humans who can no longer be sustained by current medicine. The goal of this speculative science is to resuscitate people at some point in the future and restore them to health. The US has laws prohibiting cryonics to be performed on a patient until clinical death.
The idea of clinical death has been updated several times throughout modern history. Today it is defined as cessation of blood circulation and breathing. The term is updated every time a new method of resuscitation is discovered. So far CPR, defibrillation, and epinephrine injections are able to reverse this medical condition that precedes death. For all intensive purposes, even in the US, when your undergoing cryonics your doing it at a moment before you are actually dead.
Throughout human civilization we have been fascinated with the idea of longevity and immortality. From the ancient pharaohs in Egypt to the myth of immortal vampires, it seems as if we are always looking for another way to “rage against the dying of the light.”
The theory that cryonics could work is hinged on a few basic principles. Life needs to be able to be suspended and then reanimated with its basic structure in tact. A small creature called water bears do exactly this, yet have a fundamentally different structure to our own. We do know that it is a remote possibility because people have survived extreme cold with their hearts stopped for up to an hour.
Freezing temperatures cause cracks in cellular biology, so vitrification is used to allow tissues to be cooled with little or no ice damage. Even though this process has been improved over the years, there is still a minute measure of damage that needs to be fixed before we can bring someone back.
Fixing microscopic damage is the holy grail of not only cryonics but of medical science. You may have heard of it as nanotechnology or nanomedicine. Eventually computers will become so small that they will be able to course through your veins, repairing the smallest defects and problems at a cellular level. That means no cancer, no disease and eventually a way to drastically slow down the aging process.
You might be thinking that this all sounds great in theory and that maybe your kids will have access to it on day. The shocking conclusion is that it is availible today and Alcor, the largest cryonics company worldwide, will sign you up for $150,000. The best part is you don’t even have to pay for it out of your pocket, that’s what life insurance is for.
When I heard about the prospect to open my eyes even one more time after legal death I signed up on the spot. That was over three years ago. Some people tell me that I might as well play the lottery because the odds are so far against me. Yet I believe in the advancement of science and the wonders of innovation. If I had to sign those papers again today and they stated an outrageous chance like .1% to come back to full health I would happily scribble my name in ink once more.
